It is not your smartphone. The user computer is yours but the phone is owned by the telcom. You do not have a license to operate it. The telco does. They are the owners of your smart phone. Smart phones are terrible computing devices. They are excellent shopping/bank terminals and navigational aids, but they are not allowed to compute. Set it to host a hotspot and use a real computer if you want control. A smartphone will never, can never, allow you to own it. It would be illegal.
This only runs on the user computer. It does not allow any control of the baseband modem computer. Alternate operating systems of the user computer do not change the fact that one does not own "their" smartphone.
